Russian sage, also known as Perovskia, is a beautiful and versatile perennial plant that can add a touch of elegance to any garden. One important aspect to know about Russian sage is how it grows and whether it grows on old wood.
Russian sage flowers on “new wood,” which means that the plant produces flowers on the new growth that emerges each year. This is in contrast to plants that flower on “old wood,” which refers to the previous year’s growth. Understanding this distinction is crucial for properly caring for Russian sage and ensuring its continued health and vitality.
To encourage the growth of new wood and promote abundant flowering, it is recommended to prune away the old stems of Russian sage each spring. This pruning should be done by cutting back the old stems to a height of about 6 inches from the ground. By removing the old wood, you create space for new growth to emerge and produce vibrant blooms.
In colder climates, it is not uncommon for Russian sage to experience dieback, where the stems are killed back to the ground due to frost or freezing temperatures. If this happens, do not be alarmed as Russian sage is generally hardy and can bounce back from this setback. In fact, many gardeners consider the dieback as an opportunity to rejuvenate the plant and stimulate vigorous growth.
When the stems of Russian sage are killed back to the ground, it is still necessary to prune away the dead wood in the spring. By removing the dead stems, you allow for new shoots to emerge from the base of the plant. These new shoots will eventually grow into tall, woody stems that will produce the beautiful silver-gray foliage and lavender-blue flowers that are characteristic of Russian sage.
In my personal experience, I have seen Russian sage thrive even after experiencing dieback in cold winters. The plant has a remarkable ability to recover and produce an abundance of new growth and flowers. With proper care and maintenance, Russian sage can continue to flourish for many years, providing a stunning display in the garden.
Russian sage grows on new wood, which means that last year’s stems should be pruned away each spring. This pruning stimulates the growth of new shoots and ensures abundant flowering. In colder climates, the plant may experience dieback, but it can recover and produce new growth from the base of the plant. By understanding these growth habits of Russian sage and providing appropriate care, you can enjoy the beauty and elegance of this perennial in your garden for years to come.
